I'm not sure how to phrase this, so I'll try to give an example.

My character has a whip. When the character uses the whip, he attacks with it in a circle, going in eight directions( N, NE, E, SE, S, SW, W, NW). However, instead of doing all eight directions at once - with like a FOR I=0 TO 7 LOOP - I would like a 1/2 second break in between, so I can illustrate each direction he's attacking in.

So, user attacks. It takes 4 seconds to attack total, giving me ample time to update the graphics and screen so the player can tell what's going on.

I'm using fake numbers of course, but the concept stands. What would be the best way of doing this? Instead of attacking all at once in the same frame, how can I extend said action across multiple frames?

Have it as an animation, and just play the animation.

I tend to set a "mode" that my characters are in. IE. mode 1 = can move, mode 2 = whipping stage 1, mode 3 = whipping stage 2 and so on.

Having an integer "mode" for each player and enemy makes it much quicker to run through what can and can't happen to them while in that mode. For example while whipping you don't want to be able to move so:
if player.mode=1
move_player()
else
do_whipping()
endif

I hope that makes sense!

Or, I could just do some magical trickery with AppGameKit to do the work for me

+ Code Snippet

function PlaySoundSync(pID as integer)
    i as integer
    myTime as float
    myDuration as float
    myDuration = GetSoundDuration(pID)

    for i = 1000 to 2999
        if getspriteexists(i) = 1
            stopsprite(i)
        else
            exit
        endif
    next

    playsound(pID)

    while myTime <= myDuration
        myTime = myTime + GetModifiedFrameTime()
        sync()
    endwhile

    for i = 1000 to 2999
        if getspriteexists(i) = 1
            resumesprite(i)
        else
            exit
        endif
    next
endfunction

All I have to do now is call this within my FOR loop. Depending on the action (success or failure), it will loop through until the sound is done playing. Since my current project is old-school, I disabled the sprite animation to give the illusion of non-asyncronous audio playback
